Then, require the module and use the access() method to check if a file or directory exists and you have permission to access it, as shown in the example code below:

index.tsx
const fs = require('fs-extra');

const filePath = '/path/to/file';

fs.access(filePath, (err) => {
  if (err) {
    console.error(`Error accessing file: ${err}`);
    return;
  }

  console.log('File exists and readable');
});

In the above example, we are using the access() function to check if the file at the specified path exists and is readable. If there is an error, we log the error message to the console. Otherwise, we log a success message indicating that the file exists and is readable.
